C1.3-Photosynthesis Practice-HL

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars from carbon dioxide.

Front

Which of the following is NOT a product of the light reactions? (ATP, NADPH, Oxygen, Glucose)

Back

Glucose is NOT a product of the light reactions.

Front

Where do the light reactions occur and where do the dark reactions take place?

Back

The light reactions occur in the thylakoid membrane and the dark reactions take place in the stroma.

Front

Which process in photosynthesis is directly responsible for the production of oxygen? (ATP synthesis, Carbon fixation, Calvin Cycle, Photolysis of water)

Back

Photolysis of water is directly responsible for the production of oxygen.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, which is essential for the light-dependent reactions.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to convert carbon dioxide into glucose.

Front

What is the source of carbon for the Calvin cycle?

Back

The source of carbon for the Calvin cycle is carbon dioxide (CO2) from the atmosphere.

Front

What is photolysis of water?

Back

Photolysis of water is the process of splitting water molecules into oxygen, protons, and electrons using light energy.

Front

What is the main product of the Calvin cycle?

Back

The main product of the Calvin cycle is glucose (simple sugars).
